Abstract

The plane strain fracture toughness KIC values of 2124 aluminum alloy plate of T-L and L-T orientation of thickness of 30 mm, 40 mm, and 50 mm were tested by using the standard compact tension specimen. The KIC anisotropic degree and mechanism of different thickness of 2124 aluminum alloy were studied through analyzing fracture morphology by scanning electron microscopy (SEM). The results indicate that the anisotropy of 2124 aluminum alloy plate is obvious, the differences between fracture toughness KIC of different orientation with same thickness are evident, the KIC of L-T orientation is higher than T-L orientation about 4 ~ 9 MPa·m1/2.
